About
Georgios A. Efstathiou is a researcher focused on atmospheric remote sensing and aerosol–water vapor interactions, with particular expertise in the retrieval and validation of total precipitable water (TPW) from ground-based instruments. His major contributions center on evaluating and comparing TPW data from sun photometers, microwave radiometers, and radiosondes at continental sites in southeastern Europe. In his most cited work (2019, 21 citations), he systematically assessed differences between Version 2 and Version 3 of the AERONET retrieval algorithms, providing critical insights into algorithm performance and data consistency for climate and hydrological studies. His earlier 2018 study (4 citations) laid the groundwork for these comparisons, highlighting the importance of instrument calibration and site-specific atmospheric conditions. Efstathiou’s research directly supports the improvement of satellite validation, weather forecasting, and water vapor climatology in data-sparse regions. His careful methodological approach and focus on southeastern Europe—a region with complex aerosol and moisture regimes—has made his work a reference for scientists working on integrated water vapor monitoring networks.
